Cold brew with the beans I use for filter comes out flat and papery - water temp or grind?

The bean is fighting you. Cold water pulls out much less of everything, and it is especially bad at the acids and aromatics that make a light washed Ethiopian worth drinking, so what you get is the boring middle of the coffee. Light roasts are also physically harder, so they give up less at any given time.

Two changes: brew at room temperature for twelve to fourteen hours rather than eighteen in the fridge, and use a medium roast with some body to it. Fridge brewing is slower and gentler, which is exactly the wrong direction for a bean that is already reluctant.

Which cloud free tiers are forever and which are a twelve month trial wearing a costume?

I lost an always-free Arm instance to the idle reclamation rule and it was entirely my own fault, it was a hobby bot that did roughly nothing for a week at a time.

Fix was boring: a small scheduled job that does real work every few hours, plus taking a backup of the boot volume once a month so a reclaim costs me twenty minutes instead of a weekend. If you take one of these, assume it can vanish and make that survivable.

Pi 5 with NVMe hat or a used mini PC for 24/7 Jellyfin under 200

Counterpoint for the Pi, since nobody has made it: if your library is already in a format your clients handle natively, direct play is the norm and the Pi 5 with NVMe is genuinely lovely. Silent, tiny, boots in seconds. I ran exactly that for two years. I only moved because a family member started watching on a work laptop that could not handle anything.

Pi Zero 2 W drops off wifi after a few hours until I power cycle it

Second thing to rule out is DHCP. Some ISP routers hand out short leases and the Zero 2 sometimes fails the renewal after a sleep, then sits there with no address while everything else on the board carries on. Give it a static reservation on the router side, not a static IP on the Pi, and see if the pattern changes.

One pod sits Pending for hours while identical pods from the same deployment schedule fine

Read the event string literally, phrase by phrase, because each clause is a different predicate failing on a different subset of nodes and they add up to six.

Insufficient cpu or memory means the requests do not fit in what is left. node(s) had untolerated taint means a taint. node(s) didn't match Pod's node affinity/selector means your nodeSelector. didn't match pod topology spread constraints means the skew rule. node(s) had volume node affinity conflict means the PV is pinned to a zone.

The sum across clauses will equal your node count. If two clauses account for five nodes and one for the last, you have two separate problems, which is why nine scheduled and one did not.

Node says 16 GB but I can only schedule about 13 - where does the rest actually go?

Careful with fewer bigger nodes as a conclusion. Three things bite.

Blast radius: losing one node out of three when they are large means losing a third of your capacity at once, and the remaining two have to have headroom for it or nothing reschedules.

Pod density limits: the default cap is 110 pods per node and on AWS with the VPC CNI your real limit is often the number of IPs the instance type supports, which can be far lower than the memory would suggest.

Bin packing: one enormous node is worse at absorbing a burst of medium pods than two smaller ones in some scheduling patterns, especially with anti-affinity in play.

Mid-size and more of them has been the least painful setting for us.

Two years in and people keep asking for repairs, can this pay, or does it just cover materials?

I stopped taking commissions after two years and the reason wasn't money, it was that sentimental books arrive with sentimental expectations. A family bible where the customer hasn't quite accepted that the water damage is permanent is an emotional job as much as a technical one, and I could never work out how to price the four phone calls and the disappointment. I still bind constantly, just for myself and as gifts, and I enjoy it about ten times as much as I did when it had invoices attached.
